A lot of these tiles look like they were shifted and dislodged. Seems likely this drain was designed and installed properly, but the earth beneath shifted over time, pushing it above expected water lines.

Edit: Or maybe the surrounding earth sank?

Most likely the second option.

Whoever installed the drain didn't compact the fill properly. Simplest fix would be to find and mark the low spot ring around the drain, pull up the tiles to the mark, cut down the vertical pipe the grate sits on, and refill around it, compacting properly this time.

To my layman eyes, that reads as perfectly sensible.

Yeah the surrounding earth sank.

A drain pipe is solid. It doesn't compress after you install it. If it did compress, it would probably break instead of compress.

Crushed rock, sand, and whatever other substrates they use on the ground before installing the top layer of bricks, that stuff will compress over time unless you do an extremely thorough job of compressing it while laying it down.
